Step-by-step explanation:
Rate of drainage for pump A and B = [1 pool drained]/[6 hours]
Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]
Rate for pump B (newer pump) = [1 pool drained]/[t hours]
Thus, adding the rate of drainage of A and B,
1/t + 1/15 = 1/6
t=10
Answer:
area is 21
Step-by-step explanation:
the formula to find the area of a triangle is
area = 1/2 x base x height
so we can plug the numbers of your triangle in to that formula
the base is 7 and height is 6
area = 1/2 x 7 x 6
area = 1/2 x 42
area = 21
